The purpose of this study is to identify the important factors that influence the implementation of sustainable procurement of construction works. The method used in this study is a questionnaire survey method with a Likert scale involving government procurement experts and public construction service procurement practitioners to obtain the relationship between factors and the potential success of implementing sustainable procurement of construction works. To obtain this relationship, PLS-SEM multivariate analysis was used. The results of the analysis show that the procurement process is influenced by the procurement organization and sustainable procurement policies and strategies. Sustainable procurement policies and strategies are influenced by sustainable procurement fundamentals. So, it can be concluded that the successful implementation of sustainable procurement of construction works is influenced by the fundamentals of sustainable procurement, sustainable procurement policies and strategies, procurement organization, and sustainable procurement processes.
